7.1.7. Alpine Lägerflur (Alpenblackenflur)

Rumicion alpini

Description

Phyonomy and Ecology (© Delarze & al. 2015)

Die Vegetation bildet eine üppige Hochstaudenflur aus wenigen dominanten Arten, die nicht vom Vieh gefressen werden: Rumex alpinus, Senecio alpinus, Aconitum compactum usw. Diese Hochstauden bilden durch Ausläufer flächige, ausgedehnte Bestände, die sich durch die Vitalität und Grösse der dichten Herde deutlich vom umliegenden Weideland abheben. Die Einheit gedeiht in der oberen montanen, subalpinen und alpinen Stufe auf sehr stickstoff- und phosphorreichen Böden. Solche Bedingungen gibt es normalerweise nur dort, wo sich grosse Weidetiere aufhalten. Demnach findet man das Rumicion alpini bei Sennereien, an Viehlägerplätzen und in Geländemulden, in denen sich Hangwasser aus den darüberliegenden Fettweiden sammelt. In beschränktem Mass kann es auch an Wildlägerstellen aufkommen.

Distribution map

  • Calculation method

    Current distribution: Weighted sum (number of characteristic and frequent species) per hectare based on current observations. Reported characteristic species are given a weighting of 10, while others are counted without weighting. The habitat is considered to be present in a grid cell (5 x 5 km) if it contains at least one hectare with a minimum value of 11 points.

    Potential distribution: Weighted sum (number of characteristic and frequent species) per hectare based on species distribution models. The calculation strategy is the same as for current distribution, but maps derived from species distribution models are used instead of current observations.
